k19 Claims.

This invention relates to braiding and like machines, and particularlyto carriers for the yarn packages thereof.

Altho, having certain applications and uses, in its various features,otherthan in braiding machines, or in braiding machinesvof the highspeedrotary-type, the invention is primarily intended for the more modernsuper-speedbraders, in which the package spindles are disposed inhorizontal planes, or planesfradial to the. axis of rotation of thepackage carriers. In such machines, the centrifugal forces are so greatas to tend to dislocate all of the parts, and to cause radial thrustresistance and friction between relatively movable elements, which causefracture cf the machine structure, thread breakage, interruption ofservice and other objections.

It is, accordingly, an object of the invention to overcome suchobjections and to compensate for the radial thrust effect on-thespindles and other parts, as will hereinafter more clearly appear.

Also, in such machines, as heretofore constructed, the carriers' werelimited to certain of the relatively lower ranges of the so-called highspeeds such that, if operated above such ranges, the spindles jumped, ortended to jump, out of the bearings thereof.

It is, therefore, another object of the invention to overcome thisobjection and to ensure that the spindles will stay in place under allconditions.

Further, in such machines, the spindles and packages are not ordinarilyso readily accessible for removal and replacement as in the slowerspeedmachines, in which they are freely exposed at convenient angles and onlylightly held by small snap-wire or other fasteners,

It therefore is a further object of the invention to overcome thisobjection, and to do so irrespective of any added difficulty ineifecting the result imposed by the other features of the invention,such as more securely holding the packages in place, and overcoming theadverse effects of centrifugal force.

Other objects include reducing noise, preventing service interruption,minimizing variations in, the yarn tension as the yarn is unwound fromthe packages, facilitating manipulation, ensuring a better product, andproviding a device that shall be simple and durable in construction,economical to manufacture, and effective in its operation.

With these and other objects in view, which will become apparent fromthe following detaileddescription of. the illustrative embodiments ofthe invention shown in the accompanying drawings, theinventionresidesfin the novel elementsof construction, devices, andcombination of parts in cooperative relationship, as hereln- 5 after`moreparticularly pointed out inther claims.

carrier of Imodifndforrn embodying the invention, Aand Fig.'7 is a Vewsimilar,to Fig.V 3,v ofthe carrier structure `of Fig.l 6.

Referring to ',Figs. 1.,to 5, amain carrier sup- 30 port,:Ofesubstantallydrum 0r vCnn-Sklave having` an upright perimetral ,sidewall t, is adapted for 'high-speed rotation about the vertical axisofthe cupor of its Yperimeter 9. As shown in Fig.

3,A the perimeter v9v has an annular exterior groove -35 IB, and, asindicated inFig. ,2, has Aan interior rabbet lgroove ligen a ledge l2,which carries vertical studs Ill, held by nuts l5, andsurroundedbyball-bearing elements l, I1 and. [8; Vthe Aassembly, including theparts Ill-to I8, being one 40 of several like bearing units disposedabout the ledge l2.

A frame 21B, constituting one of several like frames spaced about theperimeter 9 of the main support 8, each Vfor directly lsupporting aYyarnrl package 2|, comprises a radially-innerbase end 22, in the formof acurvedplate or-shield having atongue23 slidablyfitting the groovel0. A top extension 24 of the plate,ZZprQjeCtsradially inwardlytherefrom, over the top of the perim- 50 eter 9, to support amember I9,having abearing portion lSa for slidingmovement vin the rabbet grooveIl. The radially-innerr endmof the` frame 20, as betterseen in Fig. 4,is therefore of v invertedsubstantially U-shapein Vradial vertical 55plane section, embracing the perimeter 9 and the ledge 2 between thegrooves Ill and on which the frame 2|) moves, as a unit, in onedirection, while the support 8 moves in the opposite direction.

A flier 25, not particularly germane to this invention, operates throughthe step-by-step rota.- tion of lugs 26 olset along a shaft 2, to permitpassage of yarns between the member I3 and the shaft 2l, whilemaintaining a positive drive connection between the frame 2U, of whichthe member |9 constitutes a part, and a member 28 connected to the maindriving element of the carriers.

A seat or bearing 29, of substantially U-shape, see particularly Fig. 5,is provided on the radiallyoutwardly-facing side of the plate 22 forreceivmg an end element 30 on a spindle rod or core member 3|. A dog 33,pivoted on a pin 34, has a latch arm 35 for releasably holding thespindle end 30, and is held by a spring 36 extending between a pin 37 onthe plate 22 and an arm 38 of the dog.

The frame 20 further comprises a portion of substantially U-shape, in ahorizontal plane, Figs. l and 2, having the inner or free ends of itslegs 43 and 4| preferably integrally joined to the plate 22, and itsouter closed end 42 provided with a pivotbearing projection 43 for a pin44, Figs. 3 and 4.

The spindle rod 3| has a bifurcate or clevis end 43 embracing theprojection or eye 43, and a cylindrical thrust bearing portion 41 forcooperation with an outer nanged end 48er a sleeve 49 surrounding therod 3| and having a like ange 53 at its inner end; the anges 48 and 50con- Stituting ball races for bearing balls 5| and 52, which are heldthereto by sleeves 53 and 54. The sleeves 53 and 54 have outerperimetral grooves for the reception of annular portions 55 bentinwardly from a rotatable spindle sleeve 57, to which a disc 58 issecured for backing the package 2|. The element 30, at the inner end ofthe spindle rod 3|, is a combined nut and bearing element for holdingthe rotatable sleeve 5i on the rod and seating the device as a unit onthe bearing 29. l

'I'he arm 4i) is finished to arcuate conto-ur at its outer face andupper and lower edges, 'as seen in Fig. 5, whereby toi constitute anveasy-sliding yarn guide for a length of yarn from the package 2|, asbetter seen in Fig. 1. As viewed in Figs. l and 2, an eyelet or yarnguide 59 projects laterally from the frame leg 4| above the center of alower arcuate yarn-guide portion 60. A damper or brake element 6| forthe yarn package 2| is mounted on a pin 62, extending between aperturedlugs 63 on the leg 4| of the frame 20, and is biased to damping positionby a spring 64, which surrounds the pin 62 and is adjustable by a nut65.

In operation, the parts assume the positions shown in Figs. 1 to 3,inclusive, in which the axes The present device is, therefore,especially reinforced against such injury, by the size, weight,material, shape and location of the frames 20, Wherein'a relativelyheavy casting, preferably of iron, has its legs 40 and 4|, and itsclosed end 42, about the packages close to the center, and in theplanes, thereof, whereby to resist the radial thrust loads of thepackages in substantially the most effective manner, without subjectingany parts of the frames 20 to undue bending moment caused by said loads.

The combined thrust and radial bearing character of the anti-frictionbearings between the rods 3| and the sleeves 5l also assists indistributing the thrust loads to effectively oppose them and to providefor effective turning of the packages on the spindles. The permanentpositive connection effected, by the pin 44, and the releasable positiveconnection eifected by the latch dog 33 between the rod 3| and the frame2l), prevent the packages from jumping out of the frames under thehigh-speed strains to which they are subjected, but permit the veryconvenient and substantially instantaneous release of the spindle ends33 for moving the packages to the position indicated in Fig. 4, in whichthey may readily be slipped off the ends of the spindles forreplacement.

The arcuate yarn-guide portion 6D, which is preferably drawn about anaxis substantially normal to a plane of the axis of the package 2|, isdesigned to compensate for movement of the yarn between the eyelet 59and the constantly-changing inner-end or take-off point of the yarn;tending to lengthen the yarn between the guide 63 and the take-offpoint, as the latter approaches its center position, and tending toshorten the yarn between these points, as the take-olf point approachesits extreme position at the ends of the package. These tendencies areopposed to the natural tendency of the yarn which tendency would beallowed full play, if the guide 6U were straight along the underside ofthe frame to cause more disturbance and inequality in the tensionsystem. The guide is also positioned to hold thetake-off yarn lengthclear of the package, whereby to prevent lateral rolling or dragging ofthis length on the package, and the arcuate shape urges the yarn to movealong the package against a tendency by the package to hold it back, andas opposed to the neutral eifect of a straight-line guide.

In the preferred form of Figs. 6 and 7, in which corresponding parts aredesignated by corresponding reference characters, the parts aresubstantially identical throughout to those of Figs. l to 5, except atthe radially outer ends of the frames 25, or at the left ends as viewedin the drawings.

In this form, the closed end i2 of the U-shaped frame, instead of havingthe projection or eye 43 of the above-described form, has a radialaperture and interior screw threads 67 for the reception of acooperating exteriorly screw-threaded plug or insert 38 of substantiallycup or socketshape having a laterally-outwardly projecting inner endflange or shoulder 63; the socket being inserted, closed-end out, in theportion 42, with the flange or shoulder B9 against the radiallyinnerside of the portion 42. This construction, in which the insert 53 ispreferably of harder or better wearing metal than the frame, locks theinsert against the strong centrifugal load force of the spindle and thepackage.

Also, the radially-outer end of the spindle rod 3|, instead of havingthe bifurcated clevis pivot end i'ixed to the frame as by the pin 44 ofthe previous figures, is provided with a head 'i9 having a constrictedneck and removably fitting the socket member 58. The head 10, preferablycon- CTI structed as a ball, normally cooperates with the socket 68, asin a plug and socket joint, in which the plug head l@ is not removablelaterally from the socket. This feature, in cooperation with the latchdog 33, at the other end of the spindle, prevents the spindle andpackage from jumping out of position under high-speed operation anddirects the centrifugal load force toward a position of great strengthand ability to resist it.

When the latch dog 33 is released, the package and spindle are pivotedabout the ball-end lb, as in a ball-and-socket joint, to the position ofparts illustrated in Fig. 6, wherefrom the package and the spindle maybe removed as a unit.

The term U-shape is intended to designate any frame structure such asthat shown, or its equivalent, as an element oi the combination and forthe purposes set forth, wherein for convenience, or in view oi variablefactors of space consideration and operation, the bracket 2d, to whichsuch term applies, may depart from the purely U- shape indicated, suchas having its legs or the top edges of its legs lowered or a legdisposed beneath the package, or the structure otherwise inodiiied suchthat the outer end of the spindle is practically as weil braced againstthe centrifugal load by means exterior to the spindle, as distinguishedfrom a sole support extending from the plate 22 through the package. Theother elements are also capable of like modication and recombination, inwhich subccmbination i eares may be employed in either or both of exteiorly and interiorly-supported packages and with machines of othertypes.

f course, the improvements specically Shown and described, by which theabove results are obtained, can be changed and modiiied in various wayswithout departing from the scope of the invention herein disclosed andhereinafter claimed.
